Lesson 14: Synoptic Scale Background


Characteristics of a Developing System

A developing, or strengthening, system often exhibits one or more of the following features:

  1. The cloud band increases in brightness, the cloud water content is increasing.
  2. An S-shape develops and amplifies,
  3. An area of vorticity is located within 10 degrees latitude west, or poleward, of the baroclinic leaf, and approaches the leaf,
  4. Formation of a dry slot that expands behind the cloud band,
  5. Polar jet streak approaches the cloud band from the west-northwest direction.
